(C)︎Rie Matsuda 2025 The “Instant Meal Diet” is advocated by Rie Matsuda, who has successfully helped over 4,000 people improve their physical constitution and lose weight. Based on her unique method, she has developed a collection of “sweets that are safe to eat even while dieting.” Her first recipe book, “Easy 3-Step! Instant Meal Sweets Diet,” is now available. Traditionally, eating sweets while dieting has been considered taboo. However, this book overturns the common belief that “sweets = bad” and affirms sweets as “high-quality snacks” based on the theory of the instant eating diet. It proposes new eating habits that will help you achieve your ideal body shape and a healthy mind while eating. The key to this unique method is to effortlessly supplement nutrients that tend to be lacking in daily meals with sweets. By incorporating high-quality snacks, essential nutrients are distributed throughout the body and the mind is also fulfilled. In other words, snacking isn’t bad, it’s actually your best friend! Why not try the Instant Sweets Diet to achieve healthy, positive eating habits that you can maintain without straining yourself, and discover your ideal self?

I hope that you can enjoy “graduating from dieting” while making sweets your ally. Rie Matsuda Profile Born in 1986. Mother of two. Nurse, public health nurse, and diet instructor. Representative Director of Belle Lus Inc. and Representative Director of Belle Life Style Association. After caring for cancer patients as a nurse, she worked as a public health nurse. From her experience providing health education to adults and health guidance to patients with metabolic syndrome and diabetes, she realized that eating habits will not improve unless those who are responsible for the food at the table acquire knowledge about nutrition and the body. Drawing on her experience of naturally losing 12 kg through diet, she started her own business as a diet instructor, where she continues to work to this day. She has written numerous books, including “Lazy Instant Meal Diet.” ・Official LINE:
